I had a theme created for a website. Initially, the developers had had used a direct PHP image rotation using JQuery. We noticed that the images seemed to "flash" before the pages load. What it actually happening is that the page is displaying images in a list <li> before the page applies the CSS. So they decided to use a plugin called WP-Cycle. The problem still exists. Certain pages are worse than others, so the "flashing" is inconsistent throughout the site.
The "flashing" issue appears to be worse in certain browser than others.
I can't seem to figure out the cause, so I am offering 500 points to the person who can help me solve this (or come up with an alternate solution.
Here is the base URL. Try clicking on the news page to see the flashing:
